mention of `datarootdir' in the input file(s), but literal
`${datarootdir}' in the output file, and we haven't warned yet,
then warn as well: the user may have (erroneously) used
`AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
`AC_SUBST([mydatadir], ['${datadir}/my'])'.
* tests/torture.at (datarootdir workaround): Extend this test.
* NEWS: Update.
* doc/autoconf.texi (Special Chars in Variables): New section.
(Preset Output Variables): Warn about special chars in CPPFLAGS.
(Installation Directory Variables): Quote $(datadir) better.
(Limitations of Builtins): Describe some of eval's trickiness.
* lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
* lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
in front of every arg, not just trailing args. Quote apostrophes.
(_AC_EVAL_ECHO): New macro.
(_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
(AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
removed.
(_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
exposed by quoting of eval argument. Put the command on line line
so it logs better.
* lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
(_AC_PATH_X, AC_PATH_X): Quote more safely.
* lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
* lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
* lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
Handle special chars in prefix, ac_srcdir, ac_aux_dir.
Use eval more safely.
(_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
* lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
to be replaced.
* tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
lines, exposed by quoting of eval argument.
AC_DEFINE is now passed to m4_pattern_allow.
* NEWS: Mention that; likewise for AC_SUBST.
* lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
the parameter to m4_pattern_allow.
* tests/tools.at: Add a check for that.
ac_config_guess, ac_config_sub, and ac_configure, since evidently
some other programs unwisely rely on these undocumented vars.
But put in warning comments about them.
Problem reported by Ralf Wildenhues in
<http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
* NEWS: Document that these variables are intended to go away.
* config/install-sh: Don't use 'path' to talk about file names,
as per GNU coding standards. Close a race condition reported by Ralf
Wildenhues and Stepan Kasal. There is still a race condition
on hosts that predate POSIX 1003.1-1992, but we can't help this.
Don't mishandle weird characters like space on pre-POSIX hosts.
Invoke mkdir at most once per dir arg on pre-POSIX hosts.
* doc/autoconf.texi (Programming in M4sh): Cross-reference to
AC_PROG_MKDIR_P from AS_MKDIR_P.
(Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
from mkdir. Mention that Autoconf 2.60 install-sh is safe but
earlier editions are not (including Automake 1.8.3).
Do not suggest mkinstalldirs for thread-safety.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
presence of special characters and race conditions.
* tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
in Autoconf's name space.
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
from Automake with minor changes.
* doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
* doc/autoconf.texi (Programming in M4sh): Remove mention of
AS_VAR_SET_BASENAME, AS_VAR_SET_DIRNAME, and AS_BASENAME.
We have to keep AS_DIRNAME since it was part of a stable Autoconf,
but AS_BASENAME doesn't have to be supported.
and AS_BASENAME.
* lib/m4sugar/m4sh.m4 (AS_BASENAME, AS_DIRNAME): Bring these
back, albeit undocumented. Programs now have a grace period
to switch to AS_VAR_SET_DIRNAME and AS_VAR_SET_BASENAME.
AS_VAR_SET_DIRNAME and AS_VAR_SET_BASENAME.
* doc/autoconf.texi (Programming in M4sh): Document this. All uses
changed. The newer interfaces are more reliable, as they allow
implementations that handle trailing newline correctly. For now,
we're in a freeze, so I did not include the more-reliable
implementations, but I wanted to correct the interface before 2.60
goes out.
* lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
AS_DETECT_REQUIRED. All uses changed.
(_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
All uses changed.
(_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
(_AS_BASENAME): Renamed from AS_BASENAME. All uses changed.
Use "basename --" to protect against leading "-".
(_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
(_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
(_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
(_AS_DIRNAME_PREPARE): Likewise.
(_AS_DIRNAME): Renamed from AS_DIRNAME. All uses changed.
(_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
(_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
Use "dirname --".
(AS_VAR_SET_BASENAME, AS_VAR_SET_DIRNAME): New macros.
* tests/m4sh.at (AS_VAR_SET_DIRNAME): Renamed from AS_DIRNAME.
Test the new API. Don't test internals, since they're probably
going to change anyway.
(AS_VAR_SET_BASENAME): Likewise, renamed from AS_BASENAME.
* bin/autoconf.as: Don't use AS_BASENAME or AS_DIRNAME. This
removes a bootstrapping problem with the changes described above.
The AS_DIRNAME part wasn't used, anyway, and the AS_BASENAME
part can be done portably without all the deep Autoconf magic.
the instantiated file do not contain the string 'datarootdir'
but contain @datadir@, @docdir@, @infodir@, @localedir@, or
@mandir@, replace the reference '${datarootdir}' by the value.
* tests/torture.at (datarootdir workaround): New test.
* NEWS: Advertise this temporary fixup.
Based on a patch by Bruno Haible, reported and analyzed by
Paul Eggert and Noah Misch.

for the AC_REQUIRE mess.
* NEWS: Mention AS_CASE, AS_BOURNE_COMPATIBLE, and
AS_SHELL_SANITIZE.

and compute string lenghts with `m4_qlen' instead of `m4_len'.

* tests/m4sh.at (AS_HELP_STRING): Test extended.
* NEWS: Updated.

on the edge. However, improve the test that "pwd" actually does
report a name for the working directory.
* NEWS: Remove the claim that we test for funny chars in dir names.

due to limitations in Make syntax. Problem reported by Alexandre
Duret-Lutz.
* lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
Also, fix Tru64 porting problem with shell patterns,
reported by Ralf Wildenhues.
* doc/autoconf.texi (Particular Headers): Reword example
for multiline stdbool replacement.
(Setting Output Variables): Reword text a bit. Don't
give all the details about |#_!!_#|.
Reword description of line replacement.

newline, or "\".

ac_pwd, and quote srcdir.
* lib/autotest/general.m4 (AT_INIT): Quote file name args.
/dev/null, as "configure" shouldn't read stdin, and this insulates
us from problems (e.g., when testing for "cl"). Also, do this
redirection before invoking "hostname" or "uname", and keep the
original input stream available via...
(AS_ORIGINAL_STDIN_FD): ... this new macro.
(_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

'configure'.
